The invention relates to phenols which contain a number of aromatic nuclei and in which the bridge formation of these nuclei is in the meta-position to the OH groups. These phenols have the formula I, ##STR1## or ##STR2## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, A and n are as defined in claim 1. The novel phenols are most suitable for use as stabilizers for organic polymers and lubricants and have particularly good color properties.
本发明涉及含有多个芳香核且这些核的桥接位于OH基团的间位的酚类化合物。这些酚具有式I的结构,##STR1## 或 ##STR2## 其中R1、R2、R3、R4、A和n如权利要求1中所定义。新型的酚类化合物非常适合用作有机聚合物和润滑油的稳定剂,并具有特别优良的颜色特性。
